Syntax
$BATT
Use
This resident point is used with automation stations that can monitor the strength of their backup battery. Either a numeric value or the backup battery status indicators indicate the current status of $BATT.
$BATT numeric values are 0, 50, or 100.
- A $BATT value of 0 indicates the battery has discharged and must be replaced.
- A $BATT value of 50 indicates the battery is about to discharge and should be replaced to prevent any loss of data.
- A $BATT value of 100 indicates the battery does not need to be replaced.
$BATT status indicators are LOW, DEAD, or OK.
- If $BATT status is LOW or DEAD, then the battery has discharged and must be replaced.
- If $BATT status is OK, then the battery does not need to be replaced.
Example 1
200 IF ($BATT.EQ.0) THEN ALARM(P26BAT)
Example 2
210 IF ($BATT.EQ.DEAD) THEN ALARM(P26BAT)
See also the LOW, DEAD, and OK topics.
Notes
The PPCL runtime for PXC.A controllers considers $BATT, DEAD, LOW, and OK to be unresolved names.
